The more Luo Yi looked at the military city, the more surprised he became, He Bida took him directly to the war room, and when he entered, he could see that there was no independent office environment, and there were many areas in the war room with a screen style, all of which were beds made of simple wooden planks.

On the wall of the war room are drawings of the castle, and next to it are the topographical landmarks outside the castle and the enemy positions marked in the upper right corner of the map.

It's hard to think that the people in the war room of the military city didn't study any tactics, but they were all settling accounts, settling accounts for all kinds of engineering materials and all kinds of materials.

If he hadn't walked in from the outside and saw it with his own eyes, Luo Yi would have thought that he had gone to the wrong place, how could there be so many bookkeepers.

He Bida knew Luo Yi's doubts, and explained: "The military city is now under construction, and material statistics and material statistics are necessary. ”

What can Luo Yi say.

"This time, the Yanyun cavalry will obey the dispatch of Captain Hedu, and don't forget us in the battle if there is a charge." Luo Yidao.

He Bida agreed very politely, now that there are soldiers in the city, the way of fighting is likely to change to defending the city, and at this time, Luo Yi brought people to act as the task of charging into battle, and he was not happy.

"General Luo, let's go and rest first after a tiring journey." There are too many things to do in Hebida, and he is very happy that Luo Yi is here, but he can't delay him from doing other things.

Luo Yi is an interesting person, anyway, he has already arrived in the military city, and he is not in a hurry to understand this place.

He Bida asked Luo Yi to take him to rest, but he himself went to receive those chariot equipment, it was not the first time that Youzhou City had transported these equipment, and there were more bow and ballista carts that were used to let go.

He knew that this place was not safe, so he immediately checked all the vehicles and equipment and applied them.

The vicinity of the castle was full of people making defensive arrangements.

After the Battle of Sasu, the ambitions of the Goryeo people swelled, but they did not raise troops to attack because of this, or perhaps the vanguard came too quickly and did not give them such a chance.

A few days later, Luo Yi basically understood the situation of the military city, and gave him the impression that the defense force of the military city looked more powerful than Youzhou City, and he felt that such an investment was not cost-effective just to build such a small city.

But then he didn't think so.

After a few months of victory, the confidence of the Goryeo soldiers and horses was very inflated, and Su Gavin actually brought 100,000 soldiers and horses to attack the military city, in the eyes of their Goryeo people, as long as there were still people in the military city of the Sui State, then they would always be a threat to Goryeo and other countries.

They were waiting for the Sui soldiers and horses to attack, thinking of using the same strategy to defeat the enemy, but the vanguard did not give them a chance when they arrived.

Let the other party feel that the power is hitting the cotton, and the strength can't be used.

Su Gaiwen's mind is relatively heavy, he is an iron-fisted faction of Goryeo, and he is determined to kill all threats, and after discussion, he sent 100,000 troops to defeat the military city.

In his Su Gaiwen's plan, if the soldiers of the Sui State could be used as the outpost of their Goryeo soldiers and horses, they could defend on the spot at that time, and perhaps the territory of Goryeo could be expanded again.

"Captain, the scouts in front have come to report that 100,000 troops from Goryeo are coming towards us." The scout came over.

"Prepare for war, immediately send someone to submit the situation back to Youzhou."

He Bida is very stable, and immediately after receiving the notice, he asked all the soldiers and horses scattered outside to be properly handled, and he will not pin all his hopes on a military city.

According to the various arrangements, the vanguard was properly handled, and waited for the right person to send it to the door.

The Goryeo people didn't let He Bida wait too long, and a few days later, the Goryeo soldiers and horses waved their troops south, and at the same time the news had spread, and Emperor Yang of Sui was about to explode when he saw the Goryeo people so arrogant.

But he had no choice, there were no soldiers and horses around him who could fight except for the horses, and he actually wanted to see if these vanguard soldiers could withstand the enemy's 100,000 soldiers and horses.

Even if he can't resist it, then the Goryeo people will definitely invade Youzhou, and there will be several big battles between the two sides, he believes that the vanguard will not fail, as long as they can fight, the more beneficial it will be for his country.

Emperor Yang of the Sui Dynasty had no other perspective than Jiangshan Sheji, and people in various state capitals didn't think so, especially the sixteen states of Youji and the nearby state capitals.

It would be hard for them if the enemy came in a big way, and they all hoped that the vanguard would win the battle.

When Li De received the news, the military city had already begun to resist the enemy, and it was not difficult to guess the time of time, the vanguard of 300,000 soldiers and horses, and soon gathered 50,000 soldiers and horses, and quickly arrived at the battlefield from Youzhou.

All cavalry are equipped with two horses, the food is very sufficient, and the movement speed is quite fast, led by Shi Huaiyi, Ding Qilin, Luo Song, Xiong Kuohai, Pei Yuanqing, Cheng Zhijie and others.

The main generals with troops were Shi Huaiyi, Ding Qilin and Luo Song, and the rest only led the guards and horses.

When they arrived at the military city, the Goryeo had already attacked the city twice without success, and lost a lot of soldiers and horses, Su Gavin took the opportunity to escape with his people, but how could the tens of thousands of soldiers and horses who were ambushed behind them let them go.

Just when Luo Yi led people to encircle and suppress the Goryeo soldiers and horses, Shi Huaiyi and others happened to rush to the mountain to end the battle, which can be regarded as a meritorious achievement, and the military city gathered 100,000 soldiers and horses.

"Captain Hedu, the Koreans suffered a big loss this time, dispatching 100,000 soldiers and horses, which is more than 30,000 people, we should take advantage of the situation to pursue and completely defeat their 100,000 soldiers and horses." Shi Huaiyi proposed.

"It's not proper, you see that more than a million soldiers and horses in Sui have been calculated by the other party, we are not familiar with the terrain, and it will be out of disadvantage to go rashly, and besides, if we don't defeat them, they will always feel afraid, wouldn't it be better." Ding Qilin said.

"What do you pay attention to?" Shi Huaiyi asked.

"It's not that we are not unfamiliar with the terrain and environment, since we have arrived, let the soldiers adapt quickly and prepare for the next battle, there are many Goryeo soldiers in Liaoshui, and it is better to start by besieging but not attacking." Ding Qilin said.

He Bida and Shi Huaiyi were both thinking that Ding Qilin's method was very easy to understand, that is, to attack Goryeo in the way of the Turks, and the cavalry raid could be familiar with the environment and train at the same time, and then it could increase the tension of the Goryeo.

Use this pressure to let the Koreans show their flaws first, and then seize the opportunity to win in one fell swoop.

"Good idea, it's feasible to go to the Koreans every day to release the horses." Shi Huaiyi said.

He Bida thought about it, and at least he could be sure that the cavalry would be able to familiarize themselves with the environment faster by letting them go out to explore the road, and if it was not good, they would be able to find a new route to Goryeo.

The battle plan was quickly formulated, and the city would send 20,000 soldiers and horses to attack and harass every day, and the Goryeo people were terrified every day, and they would not be afraid if they were replaced by other soldiers and horses of the Sui State.

After the last battle, they developed the soldiers and horses they faced were very different from the previous ones, with a good record and strong combat effectiveness, and the key was cavalry.
